UNITED STATES WILLIAM DAVIS, OF CHICAGO, ILLINOIS.

DECARBONIZER.

Application filed February 23, 1926. Serial No. 89,927.

This invention has relation to means for supplying a solution or liquid to the intake manifold of an internal combustion engine or motor, whereby the gas flowing through thesaid intake, will be impregnated with a decarbonizing medium and the interior parts .of the engine or motor thoroughly cleaned, and it consists in certain peculiarities of construction, novel arrangement and combination of the various parts of the device, as will be hereinafter more fully set forth and specifically claimed.

It is well known to those skilled in the art to which my invention pertains, that the addition of moisture or liquid to the gaseous mixture of internal combustion engines produces many results or advantages, among them, a tendency, whereby carbon is prevented irom depositing on the parts direct- 1y subjected to the explosive mixture and the engine is otherwise cleaned and main- .tained in such a way as to render it more efiicient and in better running order.

It is therefore advisable, if not necessary, to frequently and thoroughly clean the motor or engine withor by means of an addition of liquid to the gaseous, explosive mixture as it passes through the intake man- 7 ifold, and to provide simple and efficient,

means for so doing is one of the objects of my invention.

Another and important object is, to provide a device of an ever ready, convenient, and compact form, which can be carried in the tool-box, orunder the seat of an automobile, or elsewhere in the car, which, when a desired to clean the motor, can be quickly at tached to a controlling valve carried by said intake manifold and positioned at its other end within almost any kind of a vessel, such as, a milk-bottle, a can, a pail or the like, supplied with a liquid such as, water and kerosene, to the end, that the latter will be automatically added to the gaseous mixture,

by reason of the constantsuction provided through the intake and device during the,

operation of the motor.

Another object of the invention is, to provide that portion of the washer adapted to be inserted in a bottle or vessel, with a floatable vmember at or near one of its ends, to hold said portion in an upright position and maintain the same position when the said portion is used in a milk bottle, or other small vessel.

Another object of the invention is to provide that portion of the device which is lnserted in a vessel with a member which is especially adapted for handling the detube with openings for the water of greater capacity than the openings for kerosene,

and to position the latter in said tube at a distance upwardly from the first named openings.

A further object is to provide a controlling valve adapted to be seated in the intake manifold of an engine in communication with the vacuum tank of the automobile,

and to provide said valve with means for readily engaging one end of the flexible portion of the washer.

Other objects and advantages of the invent-ion, will be disclosed in the following description and explanation, which will be more readily understood when read in conjunction with the accompanying, drawing, which illustrates an embodiment of which the invention is susceptible, it being understood that modifications and changes may be resorted to without a departure from the spirit of the invention, as long as they fall within the scope of the appended claims. In the drawing- Fig. 1 is a view in end elevation of a portion of a motor and its intake manifold,

illustrating in vertical section a vessel and in elevation a controlling valve and my improved washer, said valve being located on the intake and said Washer having its intake portion located in said vessel.

Fig. 2 is a view partly in section and partly in elevation of a portion of the washer and Fig. 3 is a central vertical sectional view ofthe controlling valve and a portion of the intake manifold of the engine.

Like numerals of reference refer to correviews of the drawing.

sponding parts throughout the diiferent Referring more particularly to Fig. 1, of the drawing the reference numeral 5, designates an end view of a portion of the motor of an automobile, 6, a part of the intake manifold thereof, which manifold has permanently mounted thereon and in communication therewith the casing 7, of a manually operated controlling valve 8, rotatably held in said casing and provided at its outer end with a t'ansverse part 9, to be used for opening and closing said valve and for indi- '=ating whether or not the valve is open. On the lower portion of the casing 7, and adjacent the manifold 6, is provided a nipple 10, which is externally screw threaded at its lowermost portion and is provided with a flaring seat 11, for co-operation with an annularly arranged flange 12, on a tube 13, which has communication at one of its ends with said casing and at its other end with an ordinary vacuum tank (not shown). The casing 7, is provided on its upper surface outwardly from the intake manifold 6, with another nipple 14:, in communi 'ation therewith, and of substantially the same construction as the nipple 10, just above described. The nipple 14, is provided with a flaring seat 15, for co-operation with a tapered head 16, and one end of a bent tube 17, which tube forms a part of my device, and is detachably connected to the upper end of the nipple 14, by means of a screw threaded coupling 18, swiveled on the tube 17, just above the head thereof. The tube 17, is slightly curved upwardly so that its other end will be located above, and outwardly of the key or transverse portion 9, of the controlling valve. Secured to the outer end of the tube 17, is one end of a flexible tube 19, the other end of which is secured around or to a tubular member 20, which is preferably made of metal and has mounted on its upper portion a handle or member 21, preferably, of material that will float and support at least one end of the intake member 20, of the device, so that the necessity of submerging the hand in a vessel supplied with fluid, in order to reach the intake member 20, which might be sunk therein, may be obviated.

This intake member 20, of the device, is provided in its wall with a pair of minute openings 22, which are spaced apart, and in spaced relation to the lower opening 22. with an opening 23, of greater size or capacity. The lower end of the intake member 20. of the device, is downwardly beveled as shown in Fig. 2, and has a bottom or plate 24, provided with a central opening 25, of about the same size as the opening 23, which opening as well as the opening 23, is for the admission of water, 26, while the openings 22, are principally for the admission to the member 20, of kerosene 27, with which a vessel, such as, 28, is supplied and from which said fluid will be conducted through my device and the valve casing 7, into the intake manifold 6, of the motor.

It will be understood that the vessel or container used for holding a supply of water and kerosene. which I prefer to use as an addition to the gaseous mixture of the intake manifold, may be of any suitable size, form and material, and may be located at any place within proximity to the intake manifold. It will also be understood that the kerosene will float on the water, and by reason of the location of the small openings 22, in the intake tube 20, of the device, when the suction within the same is controlled by turning the valve 8, so that its port 8, will register with the cavity of the nipple 14:, the fluid in the container will be' drawn into the said manifold, in which operation, the kerosene will enter the small openings 22, and the water will enter the larger openings 23, and 25, in the intake tube 20, and from thence be conducted to the manifold in about equal quantities.

Should the level of the fluid fall below either or both of the smaller openings 22, their minuteness will prevent the vacuum in the tube 20, being eliminated, and the fluid will continue to be withdrawn until the container is empty, it being understood, that the beveled end of the member 20, will rest on the bottom of the container, after sufficient fluid is withdrawn therefrom, and that practically all of the fluid will be caused to enter said end by reason of its novel construction.

The tube 13, is detachably connected to the nipple 10, by means of a coupling 11, swiveled on said tube around the same and slightly below its head 12, as will be readily understood by reference to Fig. 3, of the drawing.

The controlling valve 8, is rotatably mounted, as shown, in the end of the casing 7 opposite its end communicating with the manifold and is maintained in such position by means of a coupling 9, an annular Washer 9 and a spring 10 coiled around the valve stem, between the washer 9 and an annular flange 8, provided on the valve stem. The outer end of the valve stem of the valve 8, is provided with an indicating projection 9, the single point of which may be directed in such a way as to indicate when in a certain position that the valve is open.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A decarbonizer comprising a casing having communication with the intake manifold of a motor and the vacuum tank of an automobile, a controlling valve for said casing, a conduit connected at one of its ends to said casing, the other-end of said conduit being orificed and supplied with a plurality of openings in the wall of the conduit spaced apart from said end, one of said openings being oflarger size than the others, and a container to receive said latter end of said conduit.

2. A decarbonizer comprising a casing having communication with the intake manifold of a motor, a controlling valve for said casing, a conduit connected at one of its ends to said casing and means upon the other end of said conduit by which superimposed liquids in a container may be drawn at the same time through said conduit.

3. A decarbonizer comprising a casing having communication with the intake manifold of a motor, a controlling valve ior said casing, a conduit connected at one of its ends to said casing, means upon the other end of said conduit by which superimposed liquids in a container may be drawn at the same time through said conduit and means for maintaining said other end of the conduit in a vertical position.

4. A decarbonizer comprising a connection with the intake manifold of a motor said connection having communication also with the vacuum tank of an automobile, a conduit having one end attached to said connection, a valve controlling said conduit, the other end of said conduit being orificed and supplied with a plurality of openings in the wall of the conduit of difierent sizes and a container to receive said latter end of said conduit.
